I agree with what Manflex55 said regarding the tilt and 60 to 1 rule. I take it one step further by remembering that the earth is round and its horizon constantly falling. Hence, for every 60nm away a return is, you subtract 1 deg of tilt from the equation. 60 x 360 = 21600nm (pretty close to the earth's circumference). So a storm I paint with precip tops of 30,000ft at 30nm with a hypothetical tilt of 2 1/2 deg up bottom of the beam, would/should show up with 1 1/2 deg up tilt at 90nm. If it shows up at 90nm with the same tilt, it would be 6000ft higher, or 36,000ft. I used to fly a lot of 10hour flights, what else was I supposed to do with my mind?
